Abstract

A steering system hydraulics actuators (12, 13) for steering wheels (36, 37) are mechanically linked via steering arms (30, 31) and a connecting link (34). The actuators comprise cylinders (24, 25), pistons (14, 15) and hollow piston rods (16, 17). The actuators are operated in single-acting manner by connection of their head chambers (22, 23) only to a directional control valve (42) which is controlled between three positions by the pressure differential across two hydraulic control lines (50, 51). These lines are connected from a manually operated metering pump (52). Feedback connections to the lines (50, 51) are made from first feedback chambers (24, 25) on the rod sides of the pistons (14, 15). In order to overcome problems arising from differential piston velocities, the invention provides additional connections (46, 49) from second feedback chambers (26, 27) in the hollow piston rods. The second feedback chambers change volume in opposite sense to the first feedback chambers and are oppositely connected to the control lines (50, 51).
